Overview
The LM2901VQDRQ1 is a quad differential comparator from Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 2 V to 32 V and draws a typical operating current of 2.5 mA. The device features a response time of 300 ns and an input offset voltage (Vos) of 7 mV. Input bias current (Ib) is specified at 250 nA, with input offset current (Ios) at 50 nA. It supports CMOS and TTL output types and functions across a temperature range of -40°C to +125°C. The component is housed in a SOIC-14 package and holds AEC-Q100 qualification.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification
- Quad differential configuration for multi-channel signal processing
- Wide single-supply operation capability up to 32 V
- CMOS and TTL compatible output interfaces
Applications
- Automotive electronic control units
- Power management systems
- Sensor signal conditioning circuits
Procurement Notes
Verify the specific suffix QDRQ1 against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides valid traceability documentation required for automotive components. Cross-reference the ordering part number with the latest Texas Instruments release notes to account for any potential manufacturing site changes or minor specification updates that may affect integration.
Selection Notes
Select this component when high-speed comparison is required in automotive environments. The 300 ns response time suits dynamic signal monitoring tasks. Consider the SOIC-14 package constraints for PCB layout. Compare input offset voltage requirements against other series members if higher precision is needed, as this model offers standard accuracy suitable for general-purpose automotive logic interfacing.
Part Context
This device belongs to the LM2901V family, which focuses on enhanced voltage performance for automotive use. It serves as a robust alternative to standard commercial comparators in harsh environments. The quad architecture allows for compact designs in space-constrained automotive modules. It complements other TI automotive analog products by providing reliable differential comparison capabilities.
Replacement Considerations
LM2901QPWRG4Q1: Offers similar functionality but in a TSSOP-14 package with a 1.3 us response time. LM2901DR: A non-automotive grade option in SOIC-14 with comparable electrical characteristics.
